We have been receiving it at FL600 for about 20 minutes but how do you all know where it is at since it only has mode S?
MLAT or CIRCLES in Planeplotter can give you a clue of it's location.
Now that's a useful feature to include in Radarbox v4.0. If MLAT isn't possible, then sharer circles can really help pinpoint the approx. location of an aircraft.
